Letters Patent No. 98,074,

dateflvDecembe/r 21, 1869.

IMPROVEMENT IN DEVICES FOR PREVENTING- LEAKAG-E ABOUT CHIMNEYS.

The Schedule referred to in these Letters Patent and making part ot the same.

tion more fully.

Letter A, in the same, represents a chimney, provided with a wood flame-or box, B. -The same is surrounding the chimney near the roof, and resting on the same. 'lheV space between the chimney and frame or box B is filled with cement.

It will be observed, that if the frame B, as lwell as the cement enclosed by the same, is extending or projecting sucientlyover the roof, and a gutter' or gut- 'l ters are so, secured to the roof and the chimney, that the same will terminate inthe case or cement snrrounding the chimney, leakagesv around the sides of the chimney will be impossible.'

[t willalso be observed, that in order t0 carry out my invention, it is not necessary' to enclose the cement surrounding the chimney in a frame, B, but that the same maybe removed as soon as the cement has set. It can be readily seen that my invention is applicable either to new or old chimneys; that no particular'construction of chimney is required, to make use of my invention; -and, that there can be no doubtk but this invention will be received by the public most favora? bly, and that a great dealof annoyance will be avoided.v

C and D show a mere modification of B. It represents the cement protection without the frame.

Having thus fully described my invention,

WhatI desire to secure by Letters Patent, is

The combination of the adjustable box B, with the cement surrounding'the chimney, constructed and ar-.

ranged as described, and for the uses set forth'.
